Acar is traveling at a rate of 75 miles per hour. what is the car rate in miles per minute? how many miles will the car travel in 15 minutes? do not round your answers.

Now you want to set up a proportion.

1.25 miles:1 minute :: x : 15 minutes  Set up the proportion

 Cross multiply

1.25 miles * 15 minutes = x * 1 minute

18.75 miles * minutes = x * 1 minute. Divide by minutes

x = 18.75 miles. Answer

the answer is (2x+8)²= 16

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
